What is plants fertilization?
Fertilization is the process of fusion of male and female cell. In fertilization the ovary will turn into a fruit and the ovule turn into a seed.
What is the polynation?
Pollination is the process by which plants become fertilized. Pollination occurs when small grains of pollen are transferred from the male sexual organ of the plant, the anther, to the female sexual organ of the plant, the stigma. Pollination enables reproduction. Pollen blows through the air but much of the fertilization is due to bees and other insects, and some birds.
Through which process do flowers reproduce?
fertilization
Do euglenas reproduce through the process of pollination?
me yes what humma
What is the process of fertilization in flowering plants where new seeds are formed called?
Pollen germination to form the pollen tube through which the male gamets for fertilization are transferred. Simply the formation of male and female gametes sometimes termed as spores/pollens(in male plant or part) etc.
Does an aloe vera plant need to be pollinated before it produces the gel?
No, aloe vera plants do not require pollination to produce gel. Aloe vera plants are capable of reproducing through vegetative means, such as by cloning themselves from offshoots called pups. The gel is produced in specialized cells within the plant's leaves and does not involve the fertilization process.
Why does organisms that use internal fertilization produces less offspring than the ones that use external fertilization?
Because internal fertilization requires a womb and placenta to protect and nourish the growing embryos - which limits the number of offspring the mother can produce. Laying eggs outside the body means the female can potentially produce many more off-spring, and thus vastly increase the chances of the species survival.
Does the fruit develop from the stigma?
With the exception of plants that develop fruit through parthenogenesis, a stigma is required. The stigma is where the pollination or fertilization of the plant takes place.
What is fertilisation in plants?
In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination.Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel. The complete series of this process takes place in the zygote to develop into a seed.In the fertilization process, flowers play a significant role as they are the reproductive structures of angiosperms (flowering plants). The method of fertilization in plants occurs when gametes in haploid conditions fuse to produce a diploid zygote.In the course of fertilization, male gametes get transferred into the female reproductive organs through pollinators (honey bees, birds, bats, butterflies, flower beetles) and the final product will be the formation of the embryo in a seed.Fertilization ProcessIn flowers, the pollen grain germinates after the pollination of the carpel and grows into the style by creating the pathway for the pollen grain to move down to the ovary.The pollen tube opens into the ovule through the micropyle and bursts into the embryo sac. Here, the male nucleus unites with the nucleus of an egg inside the ovule forming a diploid zygote, which later swells up and develops into a fruit.Types of FertilizationFertilization process can be grouped into three types and are classified mainly based on the entry of the pollen tube into the ovule.PorogamyIt is the common type of fertilization carried out in all angiosperms or flowering plants. In this type of fertilization, the pollen tube enters the ovule through the micropyle.ChalazogamyThis type of fertilization is carried out on all Casuarina species of plants. In this condition, the pollen tube enters the ovule through the pollen tube.MesogamyThis type of fertilization is seen in all Cucurbit plants, such as pumpkin, ridge gourds, bitter gourd and other gourd plants. In this type of fertilization, the pollen tube enters the ovule through its middle part or through the integuments of the ovule.Double FertilizationDouble fertilization is a process of fertilization characterized by the fusion of a female gametophyte with two male gametes. In this mechanism, one sperm cell fuses with the egg-producing zygote, and the other fuses with the two polar nuclei to make the endosperm. All angiosperm plants undergo double fertilization process.Seed plants can go through the process of fertilization, when seedless plants cannot. If the seedless plants do go through fertilization they would require a flower for fertilization to occur.
Why are pollination and fertilization both crucial in the reproductive cycle of a flower?
Because pollination brings pollen grains to the stigma where they germinate to produce a pollen tube and male gametes traveling through this tube reach the embryo sac to perform gametic union with egg nucleus and secondary nucleus to form embryo & endosperm respectively. thus a new generation originates
What is reproduce and fertilization?
In sexual reproduction, two parents donate genes to their young, resulting in offspring with a mix of inherited genes. These genes are donated through a process called fertilization. There are two mechanisms by which fertilization can take place. The first is external (the eggs are fertilized outside of the body), and the second is internal (the eggs are fertilized within the female reproductive tract). While fertilization is necessary for organisms that reproduce sexually, individuals that reproduce asexually do so without the need for fertilization. These organisms produce genetically identical copies of themselves through the process of mitosis.
Why do animals that reproduce through internal fertilization produce fewer eggs than those that reproduce through external fertilization?
